Letters Patent No. 85,615, lated January 5, 1869.

IMPROVED MEAI-C'UTTER.

The Schedule referred to in these Letter-s Patent and making part of the same.

To all whom 'it may concern:

Be it known that I, CHAnLEs-SCHILLR, of thecity of Baltimore, and State of Marylandhave invented a new and useful Improvement in Meat-Cutters; and I kdo hereby declare the following to be a full, clear, and

exact description thereof, reference being had to the accompanying drawings, which are made a part of this specification.

My invention consists ina device, hereinafter described, by which the block upon which the meat is chopped maybe raised as the block and knives wear away by constant use, and I am also enabled to raise the block-so that the knives but just touch it, and do not bury themselves in it, so that the block and knives do not wear away as fast as in other machines.

In the drawings- Figure l represents a side elevation ofvmymachin'e. Figure. 2 is a front elevation, with the knives elek rated. v

Figure 3 is au elevation of my improved mechanism for raising the block up to the knives as the block be.- comes worn off.

Figure L .represents a plan of an extra ring,? that is placed upon -the raising-apparatus when-the block is worn away so much that it cannot be elevated high enough to reach the knives.

Figure 5 is a plan view of the bed-plate, with raising-apparatus attached.

A A'A may represent various parts of the stationary flame.

B B are fly-wheels.

C and C represent, respectively, a driving and a loose pulley on the shaft g.

I) D are connecting-rods, which connect the crankwheels E E to the cross-head F, to which the knives F' are secured.

The cross-head has secured to it, on each side 'of the machine, guide-rods H, which work in bearings h., instead of having bearings in the cross-head, to work upon stationary guide-rods,as is commonly done in other machines. -By my invention the bearings ofthe cross-head areextended to a greater distance above and below, and will be less liable to wear away and allow the knives to shake or move about, and get bent or broken, which is often the case with .machines where the guide-rods are made fast upon the stationary frame and the cross-head works upon them.

J is the block upon whichv the meatis placed to be chopped.

Rotary motion is communicated to the block J from the driving-shaft g, through the nieda of the gearing c c', horizontal shaft d, endless screw al', vertical shaft i, and gearing c c.

lhe block J may be provided, at top, with the customary rim or flange, to prevent the meat from' beingv thrown oil' while being chopped, and is provided, at bottom, with a centre-pivot, g', which turns in a suitable bearing on the bed-plate K.

The block also rests on a series of small rollers, m, supported upon a movable cam-plate, j, the cams mi', on the bottom of which, ride upon stationary cams n, secured to the bed-plate K.

. lVhen it is desired to raise the block J, the camplate j and its cams are'drawn around a'sufiicient distance by means of the crank r, endless screw s, windlass t, and chain a.

When the block and knives become worn away so much that I cannot raise the blockv high enough for the knives to take eii'ect, I place upon the bottom of the block, and upon the set of small rollers m, a ring, J', Ifig. 4, of any suitable thickness, and by this means am enabled to use the same block until it becomes too light to resist thestroke of the knives.

Having thus described my invention, l

WVhat I claim as new, and desire to secure by Letters Patent, is y 1. 'Ihe combination of the movable cams mi, camplate j, and stationary cams a, withY the block J and bed-plate K, for the purposes described.

- 2. The windlass, with the chain a, attached to one of the movable cams mt, for theI purpose of drawing the said movable cams up and around on the stationary cams n, and thus elevating'the block J any required distance, suhstantially as and for the purpose described. 3. The ring J', fig. 4, in combination with the cam-i plate j and rollers m, as and for lthe purposesekplained. To the above specification of my invention I have signed my hand, this 19th day of November, 1,868.
